Hi Dr Godbole.
I did some research on the MI Medicaid website (they do not make it easy to find information) and I found this bit of information:
Because all providers must upgrade or adopt newly certified EHRs in 2014, all
providers regardless of their stage of meaningful use are only required to
demonstrate meaningful use for a three-month (or 90-day) EHR reporting
period in 2014:
▲ Eligible Professionals (EPs) beyond their first year of Meaningful Use
must select a three-month reporting period fixed to the quarter of the
calendar year.
▲ EPs demonstrating Meaningful Use for the first time in 2014 may select
any continuous 90 day reporting period (does not need to be affixed to a
calendar quarter).
▲ Providers must attest to these reporting periods no later than February
28, 2015 at 11:59pm ET.
My interpretation is that if this is your first time for MU, then it can be any 90 Days, if it is not then it must be a calendar quarter. I will check with our MU team to see if this is uniquely a MI State ruling, or if this is nationwide.
